The convertible should have never been NA at all. The extra weight added into the chassis for strength is too much for the torqueless NA engine. 1980s insurance companies are the only reason Mazda had to mess up a good thing.

Turbo convertible > TII

 

lol I guess it is inevitiable that he will keep neck deep in modding and maintenance. MIGHT as well be with a turbo motor.


Buy a TII motor and get the swap over with.

 

 

I have always wanted a TII as most RX7 guys do... I look and look for a unmolested TII in red and good shape (as you can guess I gave up) When I found the vert, first right off the lot just ******* bought the damn car not even a mile down the road, Guy at another dealer is putting stickers up in a fresh red 91' TII for $500 more then what I had just payed for the vert... I WAS SO HAPPY! God that timing sucked. Am king of the world! O wait wtf was that? DAMN IT! haha but hey that's how life goes I guess... But I am happy with the vert, or thats what I keep telling my self haha

HOZZMANRX7 that is ******* sexy, but it would look so much better in white

What kind of package are we talking... just the motor or all you need to put it in your self or did he do the install?

 

I actually agree with you regarding white. Love white on black, no pun intended.

But Black is much more resistant to cop's lasers. Heck, smoke the FTP's and turn signals, remove the front license plate, and install a good laser shifter set up and you're practially invisable to that damn gun. Shifters are legal in your state.

I'm a Renton HS grade, by the way.

Also, here is a S5 Turbo Vert. But would take more than $3,500 to get it like this not to mention 308 to the wheel. Picture is from 7Stock. I have a better one, but it's too big to load here.

 

We all know FC are best in white but red S4's do look soo good!

My email is Uberball@yahoo.com send me any pic you have of that car it looks awesome

I almost moved to Renton a few months ago would have saved $200 a month on rent too but I decided to go to down town Bellevue...

I don't need to worry about cop's that much I am good most of the time but when I am going back home to Leavenworth, Stevens pass and the back roads are my play ground haha Cant wait to do it after the TII swap, let the real fun begin at that point I need to get invisible.

Last time I went back to Levenworth a friend of mine just got his 1st gen Miata, he said he could out corner me and would be faster... "ya your seven will be better on the straights but your owned in corner" haha so we went from Leavenworth up the Chumstick highway up to Plan then up to Lake Wenatchee and came back around threw Tumwater Canyon back in to Leavenworth... needless to say he got put back in his place haha O and good drive on a good sunny day, if anyone is around there on some random trip.

 

I would do the turbo drivetrain swap. With that said, in my experience turbo motors tend to blow up and NAs seem to run forever. I might also add my turbo engines were not stock.

Like you said a "stock" turbo vert would be pretty sweet.

agreed....that was my budget... check out sig

 

What? The mythbusters disagree: http://mythbustersresults.com/episode18.


Paint your car whatever color you want.

 

Dose anyone keep a TII stock? I mean all the people that say they have had a blow one have all messed with it some how (most of the time its just more boost) So is it a problem or is it people pushing it to much? I want to do some upgrades that would make it better and run cooler. Front mount inter-cooler, better radiator and a newer turbo but run it on the same low boost that was run from the factory.

I just had a idea could you use a RX8 tran's on a TII? would it just bolt up? The HP on a stock TII is making close to if not less then what a stock RX8 is so it should be able to handle it... and a 6 speed would be fun to play with.

 

I had a 87 TII all stock, over 200,000 on the engine before it needed to be replaced.

FMIC will restrict air flow, so restricts heat management thus engine life. TMIC or V mount would better in that regard.

New high efficient aluminum radiator absolutely a plus to Wankle engine life, especially when compared to a piston. Regular oil changes the other thing more than important thing for a Wankle than a piston engine.

Many will say a TII trans is stronger than an RX8's, but most will say putting one in a 2nd gen would be way more work that it's worth.

 

Street port the engine , buy or trade for a gtu tranny and a gxl rear , if any left buy some coil overs and call it a day

 

why dont you try to do something no one has ever done yet... like make a custom hard top for your vert.... not the greatest of ideas most might think,but its unique and would look great i would say

 

rx8 trans even tho is a 6 speed has about the same final gear ratio as the tII fc so all you really have is one extra shift point to end at the same point. save your money and TII swap the car.

I am building my car and have a spare TII motor sitting in the garage for when this one goes boom. @ 450whp and the next will be @ 500+whp

 

"I had a 87 TII all stock, over 200,000 on the engine before it needed to be replaced."

Thats what I wanted someone to say, TII will last if you dont push them or do somthing stupid to it.

"FMIC will restrict air flow, so restricts heat management thus engine life. TMIC or V mount would better in that regard."

Thats true I will keep that in mind... Know any good TMIC or V mounts?

"Many will say a TII trans is stronger than an RX8's, but most will say putting one in a 2nd gen would be way more work that it's worth."

I bet the TII is stronger... but I am not wanting to push it past both of there stock numbers so it should hold up fine.

"why dont you try to do something no one has ever done yet... like make a custom hard top for your vert.... not the greatest of ideas most might think,but its unique and would look great i would say"

I did have that idea but I just dont think it be worth it and it look like a miata haha... but I do want to do a cloth top with CF Targa I think that be cool

"rx8 trans even tho is a 6 speed has about the same final gear ratio as the tII fc so all you really have is one extra shift point to end at the same point. save your money and TII swap the car."

I take a lot of longer drives and I hate the N/A gear ratio. One seems to high and the other is to low... it just done feel right. I am hoping that the Rx8 trans fall in that happy middle and make it more enjoyable to drive.

 

This was asked not even a day or so ago, searching would give you lots of info on this...

https://www.rx7club.com/2nd-generation-specific-1986-1992-17/rx-8-6-spd-trans-881443/

and once again...

Quoted right from the 2nd Gen FAQ

Can I install the RX-8 6 speed transmission into my 2nd Gen RX-7?

"5th gear on the FE tranny is the same as the 4th on FC trannys anyway, so there is no real advantage of using the RX-8 tranny if you are thinking that the 6th gear will be a extra gear for an overdrive, and actually 6th on the FE tranny (.83 vs .71) is shorter than the FC, resulting in lower gas mileage at highway speeds.

Using a RX-8 tranny would be like adding a extra gear between 2nd and 3rd to a standard 2nd gen RX-7 M or R type transmission. If you look at the gear chart this does not match clearly, but in simplified operation it is the nearest description to what happens.

Add in, that the RX-8 6 speed transmission is also about 4 inches too short, forcing you either to relocate the shifter 4 inches forward in the car, or move the engine 4 inches backward (towards the firewall) to make it fit in the stock shifter location as well as fabricate a custom drive shaft and transmission mounts."

 

Thanks Squeeb, that kind of tosses out the tranny swap then... That damn 4 inches kind of pisses me off haha You could always play with the 6 speed gear ratio to make it how you want it... but with that you can always mess with the 5 speed too. How much of a differents is the N/a to TII gear ratio?

 

Ding ding ding. Not quite my friend. Color does indeed do nothing about radar. But a decent radar detector is more than sufficient to give advance warning so you may avoid radar no mater what car your driving.

However, not quite so with LIDAR in that a white car can be read on a Laser gun much earlie than a black car all things being the same otherwise. Ultimately its true the laser will see you, but it's all about having enough time to react to a warning and get your speed down before you become official in his guns read out.

Surf this forum http://www.guysoflidar.com/ They do tests of Laser Shifters (legal in about 46 states) and discuss what is called "push through" before the cop's gun can push through the Shifter defense. A white car with a big ol chrome grill will push through much sooner than a black 2nd gen with no front plate. More warning time is better.

 

I can't view that page since my company's filter lists it as "questionable & illegal". And this is getting off-topic, but potentially not returning a signal at long distances is hardly the same thing as being practically invisible. The cop hiding behind that sign ahead says it's still not going to matter.

 

I would save my money and move out of my parents house.

 

Try this web site then. The first one was specific to the tests, but you'll find lots of like information there.

Trust me. I personally have driven past motorcycle cops and saw them giving their guns the wtf? look (not in California). Maximum advance warning is a good thing, and sometimes very entertaining.

However, with apologies, I may have exagerated a bit when I said practically invisable.

BTW, California is the only western state where laser shifters are illegal. So the shift function must be turned off while in the Governators juristiction.

As to color, as the saying goes, once you've gone Black you'll never go back.

 

I have an 89 vert with a full S5 TII swap. Cost me a "little" more than 3500 to swap but it was well worth it.

I agree the vert should never have been an NA. All verts in Japan were turbos. The reason for US verts being NA was due to the gas guzzler tax and the fact that Mazda wanted to put automatics in the vert. The combo of TII motor and an automatic put it in gas guzzler mpg. After the early 70s bad rap Mazda and the rotary in particular got for being a gas guzzler, Mazda wanted to avoid a repeat.

I know the rotary does not get great gas mileage, but for the power a TII produces it is comparable to some HP V6s and V8s. And fyi my TII vert returned 23 mpg highway on my last 200 mile trip.

 

Its awesome not living with you parents... but I do miss moms cooking haha

**** the Governator!

I don't know about never going back, I am a equal opportunity employer

groznyiv she is awesome vary vary nice... but cost a little more then $3500? Do i want to know what a little more is haha

 

You can go about the swap to save money, but I chose to have everything rebuilt to avoid unforeseen future more painful and costly repairs. The engine was ported and all seals were replaced new, new stock turbo, new injectors all emmissions removed, new reduced ratio pulleys, new belts etc ( 3000.00). The turbo trans, S4 lsd and half shafts rebuilt etc
(1000.00). Greddy exhaust, RB 3" downpipe, magnaflow 3" resonator (700.00). 17x8 and 17x9 bbs wheels and tires and racing beat lowering springs with tokico blues (1400.00) Corksport turbo chargepipe and short throw shifter with new bushings (250.00) Altogether about 6500.00. Not too bad as the rest of the car is in excellent shape with original paint and the leather interior is in great condition. I still have the AC and power steering and everything works good. Now you might say I have more money in it than it is worth but I am not planning on selling and it is not my DD. It is well worth it to me to have a fun reliable and somewhat fast car to drive. After spending so many years with the NA engine, I wish I had not waited so long to do the swap.
